How big is the Gulf St. Vincent?
About 38,099 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Gulf St. Vincent would be land if sea level dropped?
With the sea 10 m lower, about 4,269 km² (11.2%) of its water would be land. At 6,000 m lower, 100% would be. This is a simple bathtub model that lowers the sea evenly everywhere.
